%X The application of the interference cancellation technology in satellite navigation system was presented. The limit value of the suppression ability of the interference cancellation system was analyzed. The interrelation between the bandwidth-delay product and the interference cancellation ratio was disclosed. The deterioration degree in the wideband interference cancellation ratio due to the amplitude error and phase error was quantified. Analysis was verified through simulation and experiment. It is verified that the dual antenna cancellation system can improve the interference suppression of the satellite navigation receiver by 29 dB.
